So 20=80%'
% means out of 100 so
80%=80/100 so
20=80/100
we try to get to 100/100 so
20=80/100
5=20/100
5 times 20=100 so
25=100/100

The equation that represents that line is
y=2/3x+5.
First, you have to find the slope (the change of y over the change of x which here is 2/3. Then, you put one of the points in and solve. I used (3,7) When you input them into the equation, you get 7=2/3 (3)+_ Which gives you 7=2+_ .
5+2 is seven, so the blank is 5. So, when you do that, you get Y=2/3x+5.
If you need more of an explanation, comment. The answer is the second one
Hopes this helps :)
C.2x+2+3x because you have 2x’s a 2 and 3 w’s
Given:
Amount of calories per 117.4 grams of Cereal X
<span> = 110 or </span>0.620068 per 1 gram of cereal X
Solution:
If there are 252.5 grams of cereal X then the amount of calories in it is computed as
0.620068 X 252.5
<span>156.5671 or 157 (rounded off)</span>
3v=v+6
Subtract v from both sides
3v-v = v+6-v
2v= 6
Now divide both sides by 2
2v/2=6/2
v= 3
I hope that's help:0
Lets check if the answer is good
all you need to do is to replace v by 3
3v=v+6
3(3)=3+6
9=9
The answer is good
